The following problems
can result in cracking of walls. Having addressed the foundation problem,
then the CRACKTIE can be used to reinforce the damaged wall.

Consolidation of
underlying sub-soil

Frost heave

Structural failure
of foundations

Mining subsidence

Swelling of sensitive
clay sub-soil

CRACKTIE

Attension is drawn
in the case of cavity walls to the need for transverse wall ties to be
introduced where the outer reinforced leaf is required to support the
inner loaded leaf of the wall. In many cases, it will be necessary to
utilise the REDIFIX Truss System of wall tie to ensure adequate load transfer.
If both leafs are reinforced, then only normal cavity ties such as the
MACTIE will be required.
